The plus version

I started with the free app version and loved it so much I decided to upgrade to the plus version. Because I use it so often and found myself wanting to utilize the options only the plus version offers more and more I didn't think $3.99 was too much to pay with how often I use this app. So unless this is an app you use often the free app will do just fine. However the options that are offered in the upgrade are well worth it. It really boils down to what you expect and/or want to get from the app and if your amount of usage justifies paying for it. Overall very happy with my purchase😬

No, ad-less version is not worth the $

Why? Why did I spend the money on this instead of continuing to use the free version? In retrospect they weren't so bad. Yeah it's nice to have a dictionary but fairly advanced or I should say uncommonly used words are out. Well who am I to say? No apophenia or even pareidolia. Granted I know what they mean but it doesn't leave me very financially reassured. Okay to sum up my rant if your still with me. I would go with the free version. The ads were not as big of a deal as I thought but now it's to late 😢. The "x" or delete button needs to be bigger including a fix of hit or mis load times. Overall it's just a good generic dictionary; maybe just short of great.

An Essential App & this 1 gives U ALL & More of what U need!

I've been using this Dictionary Application for MANY MANY MANY Years!! Writing a Professional Letter, Describing my Photography Business, writing contracts, & more, You can't be taken Professional if you don't spell correctly, & where I LOVE THE MOST OF THIS APP is the Thesaurus!! I get stuck on using a group of words. I count on this Thesaurus to help me write a more colorful, Artistic expression of the uniqueness of my Successful Business & how to describe how MY COMPANY treats all My Clients as All Photo Services should. Basically, get the app & upgrade to include all extras. You'll be very happy W/it!
